A Grundfos listing, from the manufacturer's published data.
| Design water flow | 6.59 kg/s |
| Power | 0.33 kW |
Open the builder and pick this listing from the catalog picker — the solver runs it with the catalog's own figures, at your design point or across a year of weather.
| Circulator curves read from vendor charts | 12 listings | curve tops within 3.5 % of each Grundfos page's P1 table; every Wilo listing under its datasheet's P1(max) |
From the validation page; every row is held by a test.
Listed from published data; a listing's figures are the manufacturer's, the model that runs them is ours. Solver results never depend on who has claimed what.
